well..i've been working on netboot for a few days now, and i've been
making little bursts of progress every now and then.  right now, i'm
stuck.

what i'm trying to do is boot a diskless box (192.168.0.4) that will
eventually act as a NAT/gateway/firewall.  i have my server
(192.168.0.3) setup right as far as i can tell.  netboot loads its
configuration fine, loads the kernel fine, and boots the kernel fine. 
when the kernel boots and tries to mount /, however, it gets an nfs
error (13,) which i think means access denied.  this makes no sense
seeing as netboot is able to use nfs to transfer the kernel.  here is a
log of what happens:

NFS ROOT: 192.168.0.3:/usr/diskless-root

the only thing that i can think of is that since netboot has already
mounted the root filesystem, the server might not like it trying to
mount the root fs again.  assuming that was the problem, i'd have no
idea how to fix it.  if *anyone* could give me *any* help, i'd greatly
appreciate it.  in case it helps, i'll include all the relevant
configuration files.  the server is fbsd 3.4-STABLE.

thank you for even *reading* this post.  if you need to contact me, my
email address is jacob@void.mapopolis.com.  if you respond to this,
please email me the response, because i'm apt to miss it otherwise.
